About us

Founded in 2006, China Energy Lithium Co., Ltd. is a high tech enterprise specializing in electrode material of lithium battery. Since its establishment, we have devoted ourselves to high tech and excellent quality, producing
electrochemical grade products, including lithium foil, lithium chip, lithium
rope, high purity lithium ingot, passivated lithium powder, lithium
aluminum alloy foil, lithium magnesium alloy foil,lithium silicon alloy

powder, lithium boron alloy, and etc. We have

always been market-oriented, adhere to continuous innovation, rapid

response to market demand, and provide high quality products and

services to domestic and foreign customers all the time. Among them, the

electrode material (lithium foil) for primary lithium battery has been

exported to many countries and regions, and our customers are all

well-known battery companies both in China and abroad. At present, China Energy Lithium is implementing the industrialization of secondary lithium

battery anode prelithiation and the third generation of secondary lithium

battery anode,and has carried out in-depth industry-university-research

cooperation with tens of international top scientific research institutes.
Our main products are with wide application in Li/MnO2 cylindrical battery, Li/SOCl2 cylindrical battery, Li/FeS2 battery, Li/MnO2 button battery,
thermal battery, and several new types of secondary lithium battery, such
as Li-sulfur battery, LMP battery, solid-state lithium battery, lithium

Super-capacitor, etc .
Since the establishment of our company, we have focused on the quality
management and system building & environmental management and
system building according to the ISO system, and we have got the
certification of ISO9001:2015, ISO14001:2015 and IATF16949:2016.

What is prelithiation?

At present, commercial lithium-ion batteries use graphite, silicon
carbon, and  silousite as the anode active material, and these
materials do not contain "lithium". The so-called pre-lithiation (lithium
supplement) means that the anode contains "lithium" before the
battery is working.
1. Why is prelithiation required?
Lithium-ion battery devices must be charged before working. The
lithium ions of  the positive electrode migrate to the anode. However,
due to the low potential of the anode, a small amount of lithium ions
will be consumed before receiving lithium ions, forming a solid state on the surface of the anode active particles.
Electrolyte interface (SEI), this part of the consumption is irreversible, so it will reduce the overall battery energy output. In order to pursue a higher energy density of the battery, it is necessary to replenish the
battery cell with lithium.
2. The pain points of the prelithiation industry?
The pain point of the battery cell prelithiation industry lies in the
precise control of the amount of lithium added, that is, the added
lithium is only used for prelithiation to form SEI. Do not overcharge the
lithium, otherwise the battery cell will "eject lithium" during the cycle,
and lithium dendrites will grow, which may pierce the diaphragm,
cause the battery cell to short-circuit and cause a safety accident. In
addition, it is also necessary to pay attention to the controllability of the
lithium replenishment process, to match the current cell preparation
process to the greatest extent, and cannot greatly or even increase
the cell preparation cost, so that the pre-lithiation process has future
market application prospects.

Pre-power battery new battle: Tesla vs. CATL?

battery suppliers launched Aligned Movement
There are not a few car companies like Tesla that build their own
battery factories.
General Motors will build a battery production base in the United
States. Mercedes-Benz has 9 battery factories in Europe, Asia and
North America. BYD has 5 battery factories in China, located in
Huizhou, Shenzhen, Chongqing, Xi'an and Qinghai. Geely owns two
battery factories in Ningbo and Jinhua, and its battery factory in
Jingzhou will be completed and put into production this year.
If car companies can achieve "battery freedom", battery companies
will face the risk of losing customers. Therefore, many battery
manufacturers have taken precautions and launched an alliance
campaign in advance.
The Swedish battery company Northvolt and Volkswagen jointly
established a battery factory. After LG Chem and General Motors
jointly established a new energy vehicle battery joint venture, they
joined hands with Hyundai. French battery manufacturer SAFT and
Peugeot Citroen Group (PSA) have jointly established two automotive power battery plants. Even Panasonic, who has fought side by side
with Tesla for 10 years, is also looking for a good partner.
